Revolutionising how people use live bacterial supplements

Probiotic science has evolved and SMART STRAINS® is leading the live bacteria revolution.

With us, taking live bacteria is no longer a billion-to-one shot…

The notion that all live bacteria have similar effects, and that you need to take one daily for your health is outdated. Just as you wouldn’t take an iron supplement to treat a vitamin D deficiency, the latest gut microbiome science tells us how important it is to get specific - we should be taking the right strain, at the right time, in the right way.
Each type of bacteria, known as a ‘strain’, has a specific purpose, and is needed in a specific dose, taken in a specific format, to have any real impact.

Why does the bacterial 'strain' matter?

When choosing a live bacteria supplement, always look out for the right strain that has been shown to be effective for your specific need (e.g. when you're on antibiotics) in human studies. If you only consider the species, it’s like choosing between a zebra and a dog - they are very different, and do very different things! The other thing to keep in mind is that more strains doesn't equate to a better product. You need to ensure each of the strains have been tested together in human studies, because just like you wouldn’t mix a chihuahua with a rottweiler without taking precautions, different strains can compete.

HCPs in serious discussion about the latest probiotic guidelines

Recommended by International Health Organisations:

The bacterial strains used in SMART STRAINS® have been carefully selected based on recommendations published by the World Gastroenterology Organisation guidelines on probiotics, leading paediatric guidelines, and world-renowned scientific reviews.

Selected strains include the World’s most published Lactobacillus strain (LGG®) and Bifidobacterium strain (BB12®).

All SMART STRAINS® strains, doses, formats and durations of use have been specially chosen to reflect those used in robust human placebo-controlled scientific trials - so you can be confident you’re taking the right strain, at the right time, in the right way.
